bent frame .........what options?

[qksilver]

I was stripping a 65 swb that i was going to use the frame and drive train under a really clean 65 LWB Big window.
Got the front end off today and was looking at the frame horns. Drivers side is straight , passengers has a kink right behind the front cross member.
I have 2 67-72 swb parts trucks, went looking and they look very close but the front frame horns are different.
Question , can I use a 67-72 frame under the 65 without changing cab and core support mounts? And what do I do about the front bumper.
I tried to find a 63-66 swb forever before i found this one. 67-72 seem to be pretty easy to find.
Thanks,
Steve
